Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

JCW had long wanted to write a new monograph on supernovae. Despite an immense
explosion in the literature and many review articles, there had not been one since that of …

The recent discovery of a Galactic fast radio burst (FRB) occurring simultaneously with an X-
ray burst (XRB) from the Galactic magnetar SGR J1935+ 2154 implies that at least some …

A luminous radio burst was recently detected in temporal coincidence with a hard X-ray flare
from the Galactic magnetar SGR 1935+ 2154 with a time and frequency structure consistent …

The theoretical fundamentals of formation of the supernova remnant (SNR) continuum radio
spectra are presented in this review. Mainly based on the Fermi 1 theory—also known as …

We construct the most complete sample of supernova remnants (SNRs) in any galaxy—the
Large Magellanic Cloud (LMC) SNR sample. We study their various properties such as …

We investigate the relation between the optical extinction (AV) and the hydrogen column
density (NH) determined from X-ray observations of a large sample of Galactic sightlines …

Supernova remnants (SNRs) in the Galaxy are an important source of energy injection into
the interstellar medium, and also of cosmic rays. Currently there are 294 known SNRs in the …

We report on the discovery of a new member of the magnetar class, SGR J1935+ 2154, and
on its timing and spectral properties measured by an extensive observational campaign …

Magnetars are a promising candidate for the origin of fast radio bursts (FRBs). The detection
of an extremely luminous radio burst from the Galactic magnetar SGR J1935+ 2154 on 2020 …
